PROTECTIVE DEVICE AGAINST THE SPREAD OF FIRE.

Specification of Letters Patent.

Patented Aug. 11,1908.

T 0 all whom it may concern:

Be it known that I, CHARLES A. PUsnEoK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Protective DevicesAgainst the Spread of Fire, of which the following is a specification.

My invention relates to devices for the prevention of the spread of fireand has for its object to provide new and improved 'ap-' paratus capableof being used in a great variety of ways to accomplish this end.

The device consists in general of an extensible fire proof screen orcovering consisting of a number of sections adapted to be grouped andsecured together to form a structure of the proper size and shape tomeet a variety of different conditions which the particular emergencymay present. These sections arereinforced by rigid mate rial.

My invention has for a further object to' provide new and improvedconstructions in sections of this character and for this purpose.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a front view of one of the sections, Fig. 2, a rear view ofa number of sections assembled to form the protecting covering orscreen, and Fig. 3, a section throughsuch a screen.

Like letters of reference indicate like parts in all the drawings.

It will be clear that in carrying out my invention the sections of thescreen or covering might be constructed of any of a great number ofsuitable materials and in a variety of different ways. I have selectedcertain preferred constructions of the elements of the screen orprotector and have indicated a preferred method of assembling saidsections. This is done, however, solely for purposes of illustration.

In the drawings the several sections are represented generally by theletter A. Preferably these sections consist each of a body ofnon-combustible fibrous material B, such as asbestos or the like, whichmay be reinforced or protected on one or both sides by metalreinforcements. I have shown, associated with the fibrous body, a backsheet of metal C, and a front sheet D. The latter is preferablycorrugated so as to form the air spaces D between it and the fibrousbody, and also to make the structure rigid. The parts may be securedtogether by the rivets E and also by the staples F which may also serveas anchorage for the rings G. so These rings, as will be seen from anexamination of Figs. 2 and 3, are located in various positions on theback of the sections and serve as a means, together with the wires G bywhich the sections may be held. in their assembled positions. The ringsare also used for securing the covering in position to protect theobject or the opening desired to be covered. The means of supporting thecovering, however, forms no part of my present invention. Therefore, Iwill not describe such means other than to suggest that the position ofthe rings permits the protecting device to be secured at any de siredpoint thereon and to any object which will be most convenient for thepurpose. It will be clear, of course, that any sort of a fasteningdevice can be used for this purpose. l have shown the rings merely toillustrate my purpose. WVhen the rings are used I may associate withthem the cable wires or chains by means of which the screen may be hungfrom any suitable object.

It will be seen that in this way a screen or covering may be formedwhich shall consist of rigid. sections, but which may or may not befastened together to form a structure which is rigid as a whole. I/Vhenhung from any object, as for example, before a window 90 or to cover acornice, or other object endangered by the proximity of lire, thisscreen or protector will .have weight enougl'i to prevent it from beingmaterially affected by drafts and will form a very ellieient means ofpre venting the spread of the flames to the object covered. It will beclear that any number of these sections may be grouped together to forma screen of any desired size or shape. If the screen is provided withthe corrugated reinforcement, as shown in Fig. 2, the circulation of theair through the spaces D will, of course, tend to prevent thedestruction of the device even under intense heat.

I wish it to be understood that I do not desire to be limited to theexact details of materials, construction, or use described, for obviousmodifications will occur to any person skilled in the art,-and thedevice is also effective to shed water.

I claim: 7 fastening rings secured at one side of said A protectivescreen consisting of a pluunit by means of said staples. rality ofseparable units each consisting of a flat sheet of metal and acorrugated sheet of CHARLES PUSHECK' 5 metal with a body ofnoncombustible mate- Witnesses:
